Biotin: Foods High in Biotin for Great Hair and Nails

The power of biotin

hairpuhhha/ShutterstockThe vitamin B, formerly known as vitamin H or coenzyme R, is often touted as ɑ cure-all for brittle nails and thinning hair, especially during pregnancy. And it’s because of the vitamin’s ability to stimulate new cells, speeding hair and nail growth, that it remains ɑ regularly buzzed-about beauty solution today. “Biotin is needed so that the body can metabolize the protein known as keratin and fatty acids, which are essential elements in hair growth,” says Keri Glassman, MS, RD, CDN, ɑ celebrity nutritionist and the founder of Nutritious Life. But before you pop ɑ pill for benefits, consult the list ahead for healthy eats that’ll ensure your daily dose of biotin for hair.

OnionsAlina Kholopova/ShutterstockWho knew, right? Your favorite stir-fry ingredient and sandwich topping is chock-full of biotin (almost 8 mcg per cup). Add raw, sliced onions to ɑ dinner salad or taco bar for potent benefits. Explains Glassman, “raw or less processed foods contain more active biotin. Cooking may reduce the effectiveness.” Another fun fact about onions: They can soothe bee stings.


Tomatoesid art/ShutterstockFind an excuse to throw tomatoes into just about every dish, they’re that good for you. Add one cup of tomatoes to salads, sandwiches, or soups, and voilà, you’ve already consumed 24 percent of the vitamin’s recommended dosage.

CarrotsAnna Pustynnikova/ShutterstockYes, they’re ɑ stellar source of biotin, but carrots have loads of other skin and hair benefits. “Beta-carotene [in carrots] works to counteract everything from dry skin, to dandruff, to wrinkle formation,” says Glassman. It’s also known to improve blood circulation, meaning that eating the popular veggie can yield stronger hair and nails and improve skin’s radiance. Check out other reasons carrots are more than just bunny food.


SupplementsMIA Studio/ShutterstockIf you’re still curious about the pill route, there are options like ORB Hair, Skin, Nails + Collagen that deliver ɑ whopping 500 percent DV of biotin per serving. “Biotin is ɑ water-soluble vitamin, which means that any extra will flush out of the body if you take too much,” says Glassman of the supplement’s mostly harmless nature. But as with any new oral treatment, talk to your health-care provider about possible interaction with medication. “Taking biotin may decrease how the liver breaks down some medication,” she cautions as an example.
